Patented Oct. 4, 1932 UNITED star ESTEL E. WILME'lI-I, OF SAN BENITO,TEXAS ROADWAY CRACK. AND JOINT FILLm Application filed August 1, 1929.Serial No. 382,677.

This invention relates to a highway fissure or joint filler, the primaryobject of the in vention being to provide a device of this characterwhich will be automatically guided along the fissure or joint beingfilled, to insure an even filling thereof, and eliminating the necessityof the operator guiding the device.

An important object of the inventionis to provide a joint or crackfiller including a container and a movable stem operating through thecontainer, the stem being of a construction to act as a guide orconductor for the material passing from the container.

Another important object of the invention is the provision of an ovalcontainer, the oval construction of the container preventing rolling ofthe container in the hands of the operator, thereby eliminating. wriststrain to the operator, and at the same time permitting the operator touse both hands.

Referring to the drawing:

Figure 1 is a side elevational view of a fissure or joint fillerconstructed in accord d ance with the invention.

Figure 2 is a sectional View taken on line 2-2 of Figure 1.

Figure 3 is a sectional view taken on line 3-3 of Figure 1.

Figure 4 is a sectional view taken on line H of Figure 1.

Referring to the drawing in detail, the de vice includes a container 5which is substantially funnel shaped as clearly shown by the The sidesof the container are slightly flattened defining a container which isoval in cross section, to the end that the container will not roll inthe hands of the operator while in use, thereby eliminating wrist strainand at the same time permitting the operator to use both hands duringthe operation of the device. 7 7

A handle indicated at 6, and which is in the form of a bail has its endssecured to the container as by means of the bolts 7, the

upper portion thereof being provided with an opening through which theupper end of the rod 8 extends, the lower end of the rod carrying theplunger valve 9, which tapers.

to fit within the tapered discharge end of the container 5.

As shown, the extremity 10 of the valve.

insuring the filling of the crack or fissure,

without smearing the material over the road surface adjacent to theopening being filled. bar indicated by the reference character 11extends across the handle or bail and has its ends secured thereto bymeans of the bolts 12. This bar is provided with an opening to receivethe rod 8, with the result that the rod may be readily and easily movedthrough the openings when it is desired to lift the valve plunger 9 fromits closed position, to allow material to pass from the container.Secured to the rod 8, at a point between the bar 11 and hail 6, is across handle 13, which may be gripped by the hands of the operator tomove the valve plunger 9 from its seat. A coiled spring 14 is disposedbetween the bail 6 and cross handle 13 and acts to normally urge the rod8 and valve plunger downwardly to close the discharge end of thecontainer, when the cross handle 13 has been released by the operator.Thus it will be seen that when the guiding extremity 10 of the valveplunger 9 is positioned in an opening or fissure being filled, and thecross handle l is moved upwardly, material will flow from the dischargeend of the contamer and pass over the valve plunger which acts as afeeder to draw the material from the container.

When the cross handle is released, it is obvious that the spring willreturn the valve plunger to itsnor n'al or closed position.

I claim:

In a device of the class described, a funnel shaped body portion oval incross section defining substantially straight sides and curved ends, abar secured to one end of the body portion to be gripped by the operatorin supporting the device, the substantially straight sides of the bodyportion being parallel to the path of travel of the body portion Whenthe device is in use, and a valve for controlling the passage ofmaterial from the body portion.

In testimony that I claim the foregoing as my own, I have hereto afiixedmy signature.

I ESTEL E. WILMETH.
